Nampa, First Ascent. The Mountaineering Association of Aomori Prefecture expedition was led by Seigo Matsushima. They took the same route which had been attempted by the British in the fall of 1970. On May 4 Susumu Takahashi and Kukuju Kimura left Camp IV at 19,350 feet on the west ridge but had to bivouac on the way. The next day the two climbers reached the summit (22,162 feet) at noon. On the way down, when they reached some steep blue ice, Takahashi suddenly slipped, fell down the north face and disappeared eternally.
